Load a raw ECG export (
Phone timestamp;…;ecg [uV], Polar-H10-style) — or generate a synthetic overnight recording to explore the full pipeline. RR, HRV, CVHR & sleep staging are all computed from the ECG.Raw ECG Input one file in · streamed & analyzed locally

RR intervals
Firmware beat-to-beat RR → validates self-computed HRV (RMSSD · SDNN · mean RR).
No RR file
Heart rate
Device HR (bpm) stream → overlaid & correlated against ECG-derived HR.
No HR file
Accelerometer
Tri-axial ACC → derived breathing (vs EDR) + motion (vs sleep stages).
No ACC file
